[0030] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0031] As described in the background technology, when the reverse osmosis membrane is actually used to filter water sources, complex pollutants such as calcium and magnesium salts, silicates, organic colloids and microbial metabolites will continue to accumulate on the concentrated water side of the reverse osmosis membrane. The accumulation of these pollutants on the reverse osmosis membrane will not only induce scaling on the surface of the reverse osmosis membrane or block the membrane pores, but may also cause the water permeability (membrane flux) of the reverse osmosis membrane to significantly attenuate, thereby affecting the effect of purifying water quality.

[0032] In the process of realizing the present invention, the applicant discovered that in industry, the reverse osmosis membrane is cleaned of surface pollutants by regularly using electrolyzed water for alkali washing and acid washing to extend the service life of the reverse osmosis membrane. However, when using household water purification equipment, the cleaning operation of regularly alkali washing and acid washing the reverse osmosis membrane is difficult, and the pH value of the detergent needs to be accurately controlled to ensure that the reverse osmosis membrane is not damaged. Therefore, it is urgent to design a method that can use electrolyzed water to clean household water purification equipment, so as to clean the reverse osmosis membrane of the water purification equipment, further maintain its water purification effect and extend the service life of the reverse osmosis membrane.

[0033] The following describes a control method for a water purification device according to an embodiment of the present invention with reference to the accompanying drawings.

[0034] For the water purification equipment provided in the embodiment of the present invention, the water purification equipment includes a filter element module and an electrolysis module. The filter element module can be a reverse osmosis membrane, which is used to filter and purify the raw water input to the water purification equipment. The electrolysis module is used to electrolyze water to further generate electrolyzed water with different acidity and alkalinity, and the generated electrolyzed water is used to clean the filter element module. The electrolysis module includes a first water outlet and a second water outlet, wherein the first water outlet is a target water outlet, which can be connected to the filter element module through a pipeline to deliver the target acid / alkaline electrolyzed water to the filter element module.

[0035] refer to Figure 1 , which is a flow chart of a control method for a water purification device provided in an embodiment of the present invention.

[0036] Step S101, obtaining the total dirtiness value of the filter element module;

[0037] Specifically, before cleaning the filter cartridge module of the water purification equipment, it is first necessary to obtain the total dirtiness value of the filter cartridge module, wherein the total dirtiness value of the filter cartridge module can represent the dirtiness of the filter cartridge module at the current moment.

[0038] Specifically, the TDS value (Total Dissolved Solids) is an indicator to measure the total amount of soluble solids in water. It is used to indicate how many milligrams of minerals, salts and other non-organic substances are dissolved in 1 liter of water. The unit is ppm (mg / L). The TDS value can be used as one of the indicators to preliminarily judge whether the water quality is suitable for drinking. The higher the TDS value, the more solid matter is dissolved in the raw water and the more impurities are in the raw water.

[0039] The contamination value can be defined as A, with the unit of ppm·s. The calculation of the contamination value can be divided into three levels according to the TDS value of the raw water. The calculation model formula is as follows:

[0040]

[0041] Wherein, T is the TDS value of raw water, in ppm; a0, a1, a2 are adjustment coefficients.

[0042] It can be seen from the above dirtiness value formula that the higher the TDS value of the raw water, the higher the dirtiness value of the filter element module.

[0043] refer to Figure 2 , which is a flow chart for obtaining the total dirtiness value of a filter element module provided in an embodiment of the present invention.

[0044] Step S201, when the water purification device is in the water outlet state, the TDS value of the raw water is obtained every second preset time period.

[0045] Specifically, since the TDS value of the raw water at any time may fluctuate when the water purification device is in the water outlet state, in order to reduce the amount of data for obtaining the TDS value but be able to approximately calculate the dirtiness value in an integral manner, the TDS value may be obtained at regular intervals, and the integral may be converted into a discrete accumulation, that is, the TDS value of the raw water may be obtained at a second preset time interval, wherein the second preset time interval may be a relatively short time such as 100ms, etc., wherein the accumulation formula per unit time may be:

[0046]

[0047] Where n is the number of times the TDS value of the raw water is obtained; T n The TDS value of the raw water obtained for the nth time.

[0048] Among them, when T n ≤100, a=a0; when 100 <T n ≤300, a=a1; when T n When >300, a=a2.

[0049] In addition, obtaining TDS values ​​at intervals is also beneficial to the accuracy of the total dirtiness value calculation. For example, if only the TDS value obtained at a certain moment when the water purification equipment is in the water outlet state is used as the representative value of the TDS value in that time period, the TDS value of the raw water fluctuates during the flow process, which may lead to large errors in the calculated value.

[0050] Step S202, determining a current dirtiness value according to the TDS value and a second preset time duration.

[0051] Specifically, according to the acquired TDS value at the current moment and the second preset time length of the interval, the dirt value contained in the raw water within the current second preset time length can be determined.

[0052] refer to Figure 3 , which is a flow chart for determining the current dirtiness value provided by an embodiment of the present invention.

[0053] Step S301, determining the adjustment coefficient according to the TDS value;

[0054] Specifically, before determining the current dirtiness value, a specific coefficient value can be obtained through repeated experiments: based on different raw water TDS values ​​producing the same total dirtiness value within a period of time, the coefficients under different TDS levels can be further determined.

[0055] The following is a specific example of how to determine the adjustment coefficient based on the TDS value:

[0056] Assume that the actual experimental data is as shown in Table 1:

[0057] Table 1

[0058] Raw water TDS (ppm) Cumulative water discharge time (s) 100 12000 200 9000 400 5000

[0059] Define the coefficient a0 as 1 at this time, and further know that the total dirtiness value at this time is:

[0060]

[0061] in, is the dirtiness value per unit time corresponding to the coefficient a0; A0 is the dirtiness value per unit time corresponding to the coefficient a0.

[0062] Furthermore, coefficients a1 and a2 are calculated based on the total dirtiness value.

[0063]

[0064] The calculated value of a1 is 0.667.

[0065]

[0066] The calculated value of a2 is 0.6.

[0067] After the adjustment coefficient is calculated, the adjustment coefficient is input into the calculation model.

[0068] It should be noted that, in the embodiment of the present invention, when calculating the dirtiness value, it is only necessary to determine the ratio of coefficients a0, a1, and a2.

[0069] Step S302: taking the product of the adjustment coefficient, the TDS value and the second preset time length as the current dirtiness value.

[0070] Specifically, the current dirtiness value is calculated according to the adjustment coefficient, TDS value and the second preset time length. For example, when the second preset time length is 100ms, the current TDS value is 120, and the adjustment coefficient a0 is 0.8, the current dirtiness value is: A=a0*T*t=0.1*120*0.8=9.6.

[0071] Step S203, accumulating the current dirtiness value to determine the total dirtiness value.

[0072] Specifically, the current dirtiness values ​​obtained are accumulated to determine the total dirtiness value. For example, assuming that the adjustment coefficient a0 is 0.8, a1 is 0.6, and a2 is 0.5, the TDS value of the raw water obtained and the corresponding water outlet time are: T0=100, t0=2000; T1=150, t1=1500; T2=200, t2=1000. Further, the total dirtiness value is calculated as:

[0073] A=a0*T0*t0+a1*T1*t1+a2*T2*t2

[0074] A=0.8*100*2000+0.6*150*1500+0.5*200*1000

[0075] A=395000

[0076] Step S102, when the total dirtiness value is greater than the preset dirtiness value, controlling the electrolysis module to run for a first preset time period to generate clean water to clean the filter element module.

[0077] Specifically, when the calculated total dirtiness value of the filter element module is greater than the preset dirtiness value, it means that the filter element module is seriously dirty and may affect the quality of the outlet water. It is necessary to control the electrolysis module to run for the first preset time to produce clean water and clean the filter element module, wherein the first preset time is the total time of the cleaning process.

[0078] It should be noted that the cleaning process of the filter module can be set to be performed when the device is in standby mode, for example, preferably in the early morning when the probability of users taking water is lower, so as to ensure that the water quality of the equipment is not affected, further ensuring the health of the user's drinking water.

[0079] As an optional embodiment, controlling the electrolysis module to run for a first preset time includes: controlling the electrolysis module to run for a third preset time at a first current, and / or controlling the electrolysis module to run for a fourth preset time at a second current, wherein the direction of the first current is opposite to the direction of the second current, and the third preset time and the fourth preset time are both less than or equal to the first preset time.

[0080] Specifically, when the electrolysis module is in operation, it will produce acidic electrolyzed water and alkaline electrolyzed water. When the electrolysis module is operated with a first current, the first water outlet of the electrolysis module produces acidic electrolyzed water; when the electrolysis module is operated with a second current, the first water outlet of the electrolysis module produces acidic electrolyzed water.

[0081] The water purification equipment can control the operation of the electrolysis module according to the specific dirtiness of the filter module as follows:

[0082] When the electrolysis module runs at the first current for the third preset time to generate acidic electrolyzed water, and only uses acidic electrolyzed water to clean the filter element module, the third preset time is equal to the first preset time; when the electrolysis module runs at the second current for the fourth preset time to generate alkaline electrolyzed water, and only uses alkaline electrolyzed water to clean the filter element module, the fourth preset time is equal to the first preset time; when the electrolysis module runs at the first current for the third preset time to generate acidic electrolyzed water, and also runs at the second current for the fourth preset time to generate alkaline electrolyzed water, wherein the order of controlling the operation of the electrolysis module with the first current and the second current can be swapped, and at this time the third preset time and the fourth preset time are both less than the first preset time, and the sum of the third preset time and the fourth preset time is equal to the first preset time.

[0083] It should be noted that the control mode of the electrolysis module according to the dirtiness of the filter module includes but is not limited to the above-mentioned embodiments. The operation mode, time and frequency need to be adjusted according to the actual situation to ensure that the filter module can be fully cleaned.

[0084] refer to Figure 4 , which is a structural schematic diagram of a water purification device provided in an embodiment of the present invention.

[0085] As an optional embodiment, the water purification device further includes a water storage tank, and a water inlet of the water storage tank is connected to the second water outlet of the electrolysis module.

[0086] Specifically, the second water outlet can be connected to a water storage tank to store non-target electrolyzed water generated by the electrolysis module for other uses. For example, after cleaning the filter module, if abnormal pH is detected in the device, the stored electrolyzed water can be used to adjust the abnormality.

[0087] As an optional embodiment, the filter element module includes a filtered water outlet and a wastewater outlet, and a wastewater valve is arranged on the wastewater pipeline connected to the wastewater outlet. The control method also includes: when cleaning the filter element module, controlling the wastewater valve to be in an open state.

[0088] Specifically, the filter element module comprises a filtered water outlet and a wastewater outlet, wherein a wastewater valve is provided on a wastewater pipeline connected to the wastewater outlet.

[0089] When normally providing drinking water to users, the wastewater valve is controlled to be powered off and closed to prevent the filtered drinking water from flowing into the wastewater pipe and causing waste of resources. After passing through the filter element module, the raw water flows to the water intake through the filter outlet, providing users with filtered and purified drinking water. When cleaning the filter element module, the wastewater valve is controlled to be powered on and opened. After the electrolyzed water cleans the filter element module, it flows into the wastewater pipe through the wastewater outlet, and the cleaned electrolyzed water is further discharged.

[0090] refer to Figure 5 , which is a logic diagram of the control method of the water purification equipment provided in an embodiment of the present invention.

[0091] Specifically, when the water purification equipment is in the water outlet state, the TDS value of the raw water is obtained, the dirtiness value of the filter cartridge module is calculated, and the total dirtiness value of the filter cartridge module is calculated based on the obtained dirtiness value, and it is further determined whether the total dirtiness value is greater than the preset dirtiness value: if the total dirtiness value is greater than the preset dirtiness value, it means that the filter cartridge module needs to be cleaned, and when the water purification equipment is in the standby state, current is input to the electrolysis module to generate electrolyzed water, and the filter cartridge module is cleaned for a preset time; if the total dirtiness value is not greater than the preset dirtiness value, it means that the filter cartridge module does not need to be cleaned temporarily, and the dirtiness value of the filter cartridge module can be continued to be obtained when the water purification equipment is in the water outlet state again, until the total dirtiness value of the filter cartridge module is greater than the preset dirtiness value, and the filter cartridge module is cleaned.

[0092] As an optional embodiment, the second water outlet of the electrolysis module is connected to the wastewater pipeline.

[0093] Specifically, the second water outlet of the electrolysis module is connected to the wastewater pipeline, so that non-target electrolyzed water electrolyzed by the electrolysis module can be discharged.

[0094] As an optional embodiment, the water purification equipment also includes an inlet and two outlet valve, a first branch, a second branch and a booster pump, the first outlet of the inlet and two outlet valve is connected to the inlet of the first branch, the second outlet of the inlet and two outlet valve is connected to the inlet of the second branch, the outlet of the first branch and the outlet of the second branch merge and are connected to the water inlet of the booster pump, the water outlet of the booster pump is connected to the water inlet of the filter element module, and the electrolysis module is arranged on the second branch.

[0095] It should be noted that the booster pump is used to increase the water pressure in the equipment pipeline so that the water can flow more quickly in the equipment pipeline.

[0096] Specifically, the water purification equipment also includes a one-inlet and two-outlet valve, the first outlet of the one-inlet and two-outlet valve is connected to one end of the first branch, the second outlet of the one-inlet and two-outlet valve is connected to one end of the second branch, an electrolysis module is arranged on the second branch, the other end of the first branch merges with the other end of the second branch, and is further connected to a booster pump, and the water outlet of the booster pump is connected to the water inlet of the filter element module.

[0097] The one-inlet-two-outlet valve is used to switch the water flow direction of the equipment according to the operating mode of the water purification equipment:

[0098] Specifically, when the water purification equipment performs water purification, the second outlet of the one-inlet and two-outlet valve is controlled to be in a closed state, while the first outlet and the booster pump are in an open state. At this time, the raw water flows through the first branch and then flows to the booster pump. The booster pump quickly provides the raw water to the filter element module, and after filtration and purification, it flows to the water intake through the filtered water outlet of the filter element module for use by users.

[0099] When the total dirtiness value is greater than the preset dirtiness value, the water purification equipment cleans the filter element module, controls the first outlet of the one-inlet and two-outlet valve to be in a closed state and the second outlet to be in an open state, and at this time, the raw water flows through the electrolysis module to generate electrolyzed water, and the target electrolyzed water generated by the electrolysis module flows to the pipeline where the booster pump is located through the first outlet of the electrolysis module, and further flows to the filter element module to clean the filter element module, and flows to the wastewater pipeline through the wastewater outlet of the filter element module, and the cleaned electrolyzed water is discharged from the wastewater pipeline; the non-target electrolyzed water generated by the electrolysis module flows to the wastewater pipeline or the water storage tank through the second outlet of the electrolysis module, and the non-target electrolyzed water is discharged from the wastewater pipeline or stored in the storage tank for other uses.

[0100] As an optional embodiment, a purification module may be further provided on the water inlet pipeline of the water purification equipment. The purification module may be a multi-stage purification device. The multi-stage purification device may include a PP cotton filter element: coarse filtration of the water flow can effectively intercept large suspended particles such as silt, rust, etc.; an activated carbon filter element: removes residual chlorine, foreign color and odor, and some organic pollutants through physical adsorption and chemical catalysis; a precision filter membrane or ultrafiltration membrane: further intercepts microscopic impurities such as microorganisms and colloids. In addition, for areas with harder water, the purification module may also be equipped with an ion exchange resin filter element to reduce the concentration of calcium and magnesium ions in the water flow, which can effectively prevent scaling of the electrolysis module. By providing a purification module, the electrodes of the electrolysis module can be protected from corrosion by impurities. In addition, the conductivity of the purified water is more stable, and the electrolysis efficiency can be significantly improved.

[0101] It should be noted that the purification module can also be arranged between the water filter outlet and the water inlet of the filter element module to purify the water passing through the filter element module again, thereby further ensuring the safety and health of the drinking water obtained by the user.

[0102] According to the control method of the water purification equipment provided by the embodiment of the present invention, while purifying and filtering the water source and providing it to the user, the dirtiness of the filter element module can be calculated according to the TDS value of the water source, and the electrolysis module can be further controlled to generate corresponding electrolyzed water to clean the filter element module according to the dirtiness of the filter element module, thereby realizing intelligent cleaning of the filter element module, effectively extending the service life of the filter element module, further ensuring the water purification effect of the water purification equipment, and ensuring the health of the user's drinking water.
